Unity jump from one canvas scene to another scene with canvas

Delete the EventSystem object in your second scene. As the error suggests you're only supposed to have one EventSystem active at a time

You should normally be fine with one EventSystem in each scene, but it will fail if:

• The GameObject with the EventSystem is DontDestroyOnLoad

• You are loading the second scene additive (SceneManager.LoadScene("Scene", LoadSceneMode.Additive);)

Either change the above or remove the EventSystem from the scene that gets loaded.
